Page 4: About These Guidelines
About these guidelines The purpose of these application guidelines is to provide guidance in the application of Copeland™ ZX Small outdoor refrigeration units. They are intended to answer the questions raised while designing, assembling and operating a system with these products. -
Page 5: Safety Statements
Safety statements ▪ Refrigerant compressors and refrigeration units must be employed only for their intended use. The system has to be labelled according to the applicable standards and legislation. ▪ Only qualified and authorized HVACR personnel are permitted to install, commission and maintain this equipment. -
Page 6: Product Description

2.8.2 ZXLE models IMPORTANT Absence of insulation on the liquid line in ZXLE units! Air moisture condensation and lack of performance! Moisture will condensate on the liquid line and cause water droplets. The liquid line can pick up additional heat from the ambient which will adversely affect the subcooling desirable for the liquid refrigerant before it enters the expansion valve. -
Page 11: Main Components Description
The housing is designed to withstand a 300-hour salt spray test according to ASTM B-117, ASTM-1654 and ČSN EN ISO 9227. NOTE: For detailed information about unit components and spare parts, please refer to the compressor application guidelines and to the Copeland Spare Parts & Accessory Catalogue available at www.copeland.com/en-gb/tools-resources.

Page 12: Main Control & Safety Features
2.10 Main control & safety features Copeland ZX Small refrigeration units feature a whole range of control and safety components. 2.10.1 Suction pressure control The unit is switched on and off by means of a PS1 low-pressure switch. Caution: The unit does not have any cycling protection. The adjustment of the low-pressure switch must be done in such a way that the unit will not switch on and off more than 10 times per hour during normal operation. -
Page 13: Installation
Copeland ZX Small refrigeration units are delivered with a holding charge of dry air at 1.68 bar. The refrigeration unit should be located in a place such that any dirt, dust, plastic bags, leaves or papers are prevented from covering the condenser and its fins. -
Page 14: Refrigeration Piping Connections
Refrigeration piping connections 3.2.1 Refrigeration piping installation WARNING High pressure! Risk of personal injury! The units are pressurized with dry air. Be careful when opening connections on a pressurized item. IMPORTANT Tubing quality! Installation contamination! All interconnecting piping should be of refrigeration grade, clean, dehydrated and must remain capped at both ends until installation. -
Page 15: Brazing Recommendations
3.2.2 Brazing recommendations CAUTION Blockage! Compressor breakdown! Maintain a flow of oxygen-free nitrogen through the system at very low pressure during brazing. Nitrogen displaces the air and prevents the formation of copper oxides in the system. If allowed to form, the copper oxide material can later be swept through the system and block screens such as those protecting capillary tubes, thermal expansion valves, and accumulator oil return holes. -
Page 16: Electrical Connection
DIN EN 60204-1. Also, the voltage drops and temperature on line must be considered for cable selection. Copeland ZX Small units are designed for 220-240 V / 1 Ph / 50 Hz power supply. A voltage tolerance of ± 10 % is acceptable. -
Page 17: Maximum Operating Currents For Cable Selection
11.8 A Table 11: Unit maximum rated currents for cable selection 3.3.3 Electrical protection standard (protection class) The protection class of the Copeland ZX Small unit is IPX4. 3.3.4 Main fuses WARNING Main switch "On"! Electrical shock hazard! Before changing the fuses, turn the isolating switch off to de-energize the unit. -
Page 18: Location & Fixings
Location & fixings IMPORTANT Dust and dirt contamination! Unit lifetime reduction! The unit should always be installed in a location where clean airflow is ensured. External fouling of the condenser fins leads to high condensing temperatures and will reduce the lifetime of the unit. It is required to maintain a clearance of 300 mm between the wall (or the next unit) and the unit left and rear panels while a clearance of 500 mm must be maintained from the unit right, top and front panels (seen facing the front of the unit) –... -
Page 19: Start-Up & Operation
Start-up & operation Before commissioning, ensure that all valves on the refrigeration unit are fully opened. Evacuation CAUTION System pressure below atmospheric pressure! Compressor damage! Never energize the unit without minimum refrigerant charge in the system. There is a risk of malfunction of the unit in deep vacuum operation which can cause compressor damage. -
Page 20: Oil Charging Procedure
4.2.2 Oil charging procedure Copeland ZX Small refrigeration units are supplied with a compressor oil charge only. After commissioning, the oil level should be checked and topped up as necessary. NOTE: The oil level should be approximately halfway up the sight glass. -
Page 21: Rotation Direction Of Scroll Compressors
Rotation direction of scroll compressors Scroll compressors, like several other types of compressors, will only compress in one rotational direction. Direction of rotation is not an issue with single-phase compressors since they will always start and run in the right direction. Maximum compressor cycle Maximum permitted starts per hour: 10. -
Page 22: Maintenance & Repair
▪ Release the compressor mounting parts then lift the compressor and replace it with the new one. NOTE: For more information about unit components and spare parts, please refer to the compressor application guidelines and to the Copeland Spare Parts & Accessories Catalogue available at www.copeland.com/en-gb/tools-resources. Safety devices During regular maintenance, all mechanical safety devices such as high- and low-pressure switches must be checked for proper functioning and triggering at adjusted setpoints. -
Page 23: Electrical Connections
All condensing units will generate some degree of vibration. Copeland ZX Small units are no exception. However, the vibration level from the compliant scroll technology is less severe than in units using reciprocating compressor technology. -
Page 24: Certification & Approval
− EN 61000-6-3: Electromagnetic compatibility (EMC) Part 6-3: Generic standards – Emission standard for residential, commercial and light-industrial environments. ▪ The Copeland ZX Small refrigeration units and their piping comply with the Pressure Equipment Directive PED 2014/68/EU.
